chrome、ff下flash的mousewheel事件失效(wmode=transparent)

目前想到的解决方法，监听页面的鼠标中轮事件，然后回传给flash

 

function addEvent(elem, type, handler) {
    type = type.replace(/^on/, '');
if (elem.attachEvent) {
        elem.attachEvent('on' + type, handler);
    } else if (elem.addEventListener) {
        elem.addEventListener(type, handler, false);
    }
}

//支持非IE、firefox浏览器
!(function() {
var swfEl = getEl('God_main');
var ua = navigator.userAgent.toLowerCase();

if (swfEl.addEventListener && !/(ie|opera)/.test(ua)) {
var eventType = /firefox/.test(ua) ? 'DOMMouseScroll' : 'mousewheel';

        addEvent(swfEl, eventType, handleWheel);
    }
})();

function handleWheel(event) {
var delta = /firefox/.test(navigator.userAgent.toLowerCase()) ? -event.detail : event.wheelDelta/40;

var swfEl = getEl('swfId');

    swfEl.mouseWheel(delta);
}

AS中添加代码：

ExternalInterface.addCallback('mouseWheel', mouseWheelCallback);
